Description

Pipeline elbow heat preservation shell Technical Field The utility model relates to the technical field of heat-insulating shells, in particular to a heat-insulating shell for a pipeline elbow. Background In industries such as petroleum, chemical industry, electric power, heat supply and the like, a pipeline system is generally used for conveying high-temperature or low-temperature media (such as steam, hot water, refrigerating fluid and the like), and an elbow is used as a key component in the pipeline system, and because of the special geometric shape of the elbow, the elbow is easy to be a weak link of heat loss or external heat invasion, so that effective heat preservation treatment on the elbow is an important means for reducing energy loss and improving system efficiency. Traditional heat preservation shell usually needs to customize according to the specific size and the shape of elbow, and the installation involves a plurality of steps (such as cutting, concatenation, fixed etc.), and complex operation and consuming time because the size, angle and the camber of pipeline elbow are different, and traditional heat preservation shell often is difficult to laminate elbow surface completely, leads to the heat preservation inhomogeneous or has the clearance, influences the heat preservation effect. Disclosure of utility model The utility model aims to provide a pipeline elbow heat-insulating shell, which can effectively enhance the overall rigidity and stability of a flexible shell by taking a plastic protective cover as an internal supporting structure, prevent the shell from deforming under external pressure or vibration, ensure that the shell is more convenient to assemble by the internal design of the plastic protective cover, simultaneously facilitate the subsequent inspection, supplementation or replacement of heat-insulating materials, reduce the maintenance cost, ensure that the plastic of the plastic protective cover can adapt to pipeline elbows with different shapes and sizes, and improve the universality and applicability of the shell. In order to achieve the purpose, the pipeline elbow heat-insulation shell comprises a flexible shell, wherein four connecting columns are fixedly connected inside the flexible shell, a plurality of one-way injection valves are arranged among the four connecting columns, one end, far away from the flexible shell, of each connecting column is fixedly connected with a plastic protection cover, one end of each plastic protection cover is fixedly connected with a protruding block, grooves are formed in the plastic protection cover, and a plurality of matching plates are fixedly connected to the outer surface of each plastic protection cover. The design enhances the structural stability of the shell, is convenient to install and maintain, and improves the heat preservation effect and the service life. According to the pipeline elbow heat-insulating shell, the one-way injection valves are positioned above the matching plates, and the number of the one-way injection valves is correspondingly set with the number of the matching plates. The layout ensures the coordination work of the injection valve and the matched plate, improves the uniform distribution of the heat insulation material and enhances the heat insulation effect. According to the pipeline elbow heat-insulating shell, the unidirectional injection valves and the connecting columns are arranged in a staggered mode, and the connecting columns are distributed on the outer surface of the plastic protective cover in an array mode. The staggered arrangement optimizes space utilization, improves the compactness and stability of the structure, and is convenient to install and disassemble. According to the heat-insulating shell of the pipeline elbow, the positions of the protruding blocks and the grooves are matched, and the protruding blocks are located above the grooves. The design ensures the tight connection of the shell, prevents the leakage of the heat insulation material and improves the integral tightness and heat insulation performance.
